The monotypic genus, Bellojisia (Höhn) Réblová was established by Réblová (2008), to accommodate Bellojisia rhynchostoma (Höhn.) Réblová (= Jobellisia rhynchostoma (Höhn). Barr) as the type species. It is saprobic on wood. Based on phylogenic analyses of LSU sequence data Jobellisia rhynchostoma formed a distinct clade from the other species of Jobellisia in Jobellisiales and this species was placed in Lasiosphaeriaceae, Sordariales (Réblová 2008), Bellojisia rhynchostoma is different from other species of Jobellisia based on phylogenetic analysis and some morphological characters such as its unique reniform ascospores, deliquescing asci, ascal apex and the structure of the perithecial wall ( Réblová 2008).
Type species: Bellojisia rhynchostoma (Höhn.) Réblová

Bellojisia rhynchostoma.is characterized by a stromatic perithecia with elongate necks and superficial to semi-immersed pyriform venters and a carbonaceous three-layered perithecial wall. Ascospores are hyaline, later brown, and reniform to navicular with a polar germ pore and have 1-septate that formed in unitunicate asci. Bellojisia rhynchostoma was not observed to produce an asexual morph in vitro and is distinguished within the Sordariales by its reniform to navicular, 1-septate, brown ascospores with a polar germ pore, cylindrical asci that evanesce early, conical to pyriform perithecial venter with large firm neck and pseudoparenchymatous perithecial walls. The morphology of the surrounding three-layered perithecial wall with an externally formed tomentum is consistent among the patterns seen in Lasiosphaeriaceae. The appearance of a tomentum on the perithecial surface occurs several times in the evolutionary history of the Sordariales, which is typical for members of the Lasiosphaeria clade (Miller & Huhndorf 2004).
